Empirical Validation of a Biogas Plant Simulation Model and Analysis of Biogas Upgrading Potentials
Energies, 2021 Biogas plants may support the transformation towards renewable-based and integrated energy systems by providing dispatchable co-generation as well as opportunities for biogas upgrading or power-to-X conversion.

Biogas Upgrading by Transition Metal Carbides [PDF]
ACS Applied Energy Materials, 2017 The separation of carbon dioxide (CO2) from methane (CH4) is critical in biogas upgrading, requiring materials with high selectivity toward one of the two gas components. Hereby we show, by means of density functional theory based calculations including dispersive forces description, the distinct interaction of CO2 and CH4 with the most stable (001 ...

Ecosustainable biomethane and fertilizerproduction through anaerobic co-digestionof animal manure and energy crops [PDF]
, 2012 In Italy and many European countries energy production from biomass is encouraged by strong economic subsidies so that renewable energy plants, anaerobic digestion plant producing biogas in particular, are getting large diffusion.

Recent trends and advances in biogas upgrading and methanotrophs-based valorization
Chemical Engineering Journal Advances, 2022 The global quest for sustainability in industrial activities and waste management has recently boosted biogas production worldwide. However, the rapid decrease in the levelized cost of electricity of renewable energies will soon entail electricity prices

Thermodynamic, kinetic and dynamic aspects of biogas upgrading using nano-engineered grazynes
, 2022 Different nano-engineered grazynes have been studied as possible membranes to separate methane (CH4) from carbon dioxide (CO2) by computational simulations based on density functional theory (DFT) and molecular dynamics (MD).

Coking in a two-stages catalytic upgrading of biogas [PDF]
, 2023 openBiogas, essentially a mixture of CH4 and CO2, obtained from the fermentation of waste and a subsequent purification, is exploited selectively separating the methane from the carbon dioxide, through different technologies. The result is the production

Alternative of Biogas Injection into the Danish Gas Grid System—A Study from Demand Perspective
ChemEngineering, 2018 The Danish government has set an ambitious target to achieve 100% fossil independence across all energy sectors, which demands optimum utilization of renewable energy sources, such as wind and biogas, by 2050.

Angewandte Chemie, EarlyView.A critical step, dry reforming of methane (DRM) converts biogas into useful syngas. Yet trace H2S in biogas rapidly poisons DRM catalysts, limiting practical use. We developed a robust Pt/CeO2 catalyst sustaining DRM activity via CO2‐induced reverse lattice oxygen spillover in H2S‐rich environments.

Porous Organic Cages for CO2 Capture and Confined Reduction
Angewandte Chemie, EarlyView.Porous organic cages (POCs) enable the coupling of CO2 capture and conversion through the interplay of molecular structure and solid‐state organization. Beyond intrinsic cavities, packing‐dependent pore accessibility and mass transport govern local CO2 concentration and catalytic performance, linking adsorption to reactivity in integrated capture ...

Chemical Engineering Transactions, 2017 In Malaysia, one of the source of biogas is from anaerobic digestion of palm oil mill effluent (POME). This biogas trapped is upgraded to biomethane by removal of CO2 and other unwanted components.
